The two barnstormed across Massachusetts in recent days leading up to the election on Tuesday, Nov. 8, but the race was never close.
Democrat Healey held a double-digit lead over the former longtime Republican politician for months leading up to Tuesday's vote. In the end, she collected about 63 percent of the vote while Diehl won around 35 percent, CBS Boston reports citing projected results from the Associated Press.
The Harvard-educated Healey picked up several key endorsements early in the campaign, with politicians such as Boston Mayor Michelle Wu and Sen. Elizabeth Warren throwing their support behind her.
She also found allies with unions and organized labor, with several of them endorsing her candidacy. Those included the National Association of Government Employees and the Massachusetts Teachers Association.
Healey was one of several women vying for governorships and other top state offices around the country such as Democrat Tina Kotek in Oregon and Republican Sarah Huckabee Sanders in Arkansas among others.
Healey's historic win also means Massachusetts has its first-ever all-female team in the executive branch. Salem Mayor Kimberley Driscoll, Healey's running mate, will serve as the state's lieutenant governor.
The results come after former Governor Charlie Baker decided to run for re-election in 2021. He has served as the Commonwealth's governor since January 2015. Healy's appointment also marks a gubernatorial from a Republican to Democrat in Massachusetts.
